HA 구성
DeepFinder HA 구성
DeepFinder Manager는 Server, Postgres HA 구성을 통해 Active 서버 장애 시 Standby서버가 동작할 수 있도록 구성할 수 있습니다.
HA 구성 후 Active 서버의 고장 등으로 인해 네트워크 연결이 불가능해지면 Standby 서버가 Active 서버 역할을 수행함과 동시에 연결이 끊어진 Agent는 Standby 서버로 통신을 요청합니다.
Server Process HA 구성
1) 설치 파일 다운로드
Repository에서 DeepFinder Manager Server 설치파일을 다운로드 합니다.
[root@localhost~]# wget http://download.deepfinder.co.kr/DeepFinder/dfServer/DFServer.tar.gz2) 압축 해제
다운로드 된 설치파일의 압축을 해제합니다.
[root@localhost~]# tar xvfz DFServer.tar.gz3) 스크립트 실행
설치 스크립트 실행압축이 해제된 디렉토리에 진입하여 설치 스크립트를 실행합니다.
[root@localhost~]# cd DFServer
[root@localhost~]# ./setup.sh

1. modify config.xml
2. cp license.txt /usr/local/dfserver/license/
3. service dfserver startServer Active 설치
[root@localhost DFServer]# ./ha.sh master 192.168.3.8
Redirecting to /bin/systemctl restart dfserver.service
Server Standby 설치
[root@localhost DFServer]# ./ha.sh slave 192.168.3.58
Redirecting to /bin/systemctl restart dfserver.service
Postgres HA 구성
1) Postgres 포트 오픈
Active - Standby Postgres 간 통신을 위해 Active 서버 내 Inbound Port 5432 를 허용합니다.
Danger
Inbound 5432 Port 오픈 시 반드시 Master/Standby 서버 IP만 허용하시기 바랍니다.
2) Postgres Active 서버 설치
[root@localhost DFDB]# ./setup_postgres.sh master

3) Postgres Standby 서버 설치

4) pg_hba.conf 수정
Active 서버와 Standby 서버의 Postgres 통신을 진행하기 위해 각각의 postgres - pg_hba.conf를 수정합니다.
host의 IP를 서로 통신할 서버 IP를 입력합니다.
수정 후에는 postgres를 재시작하여 수정된 내용을 적용합니다.
[root@ip-172-31-12-31 ~]# cat /usr/local/dfserver/postgres/data/pg_hba.conf
